  • Motors and Drives: A Practical Technology Guide
    was equal to or smaller that its DC counterpart. Improvements in power electronics increased the reliability of AC drives, to the point where one would almost never hear of a drive failure upon start-up. This book is intended to de-mystify drive and motor technology, used in today's modern
  • AC-DC Conversion
    . As such, the power flow can only be from the utility AC side to the DC side. A majority of applications such as switching DC power supplies, motor drives, servo drives, and so on, use such uncontrolled rectifiers. In most of these applications, the rectifiers are supplied directly from the utility
  • AC Technology Introduces Model 940 PositionServo
    AC Technology, a member of the Lenze Group, announces the release of its Model 940 PositionServo Drive. The new PositionServo is described by the company as combining a high-performing servo drive with a simple, yet robust motion controller and is available at an incredible low price. a member
  • April 21, 2009 - Wind-turbine drive takes the prize at Hannover Fair
    of simple ac drives for permanent-magnet motors up to 7 kW. Used with permanent-magnet ac motors without speed sensors, the AC650S Series reportedly offers energy savings and a more-compact size compared with conventional systems based on induction motors. Target applications include fans, pumps
  • Filling On The Fly
    The Allen-Bradley 1394 digital servo controller is a position controller integrated within a modular, digital AC servo drive, providing a single, compact, motion-control package. Machine builders clearly understand that their customers' requests are thinly veiled demands. Either the builder meets
  • Medical Device Link .
    with a cone-locating system for accurate tramming of multiple cabinets. 11501 Eagle St. N.W., Coon Rapids, MN 55448. Designed for medical tubing, a coordinated, fully programmable coiling machine allows quick coiler response. The dual-axis, ac servo drive system allows for ratios in excess of 2000:1
  • Servosystem switches cartons with ease and speed
    the carton flaps. Seven Bosch EcoDrive Cs drives and MSM compact ac servomotors synchronize, cam, and glue. A Sercos digital fiber-optic network provides a 32-bit command signal and diagnostic feedback from each ac servo in the system. Rather than a traditional PLC, the machine is controlled
  • Medical Device Link .
    High Power in Compact Dimensions: Servomotors Available in both ac and dc currents, servomotors consist of a motor, gearbox, and regulating electronics. They have two inputs: an energy source for the motor and a command source, such as an encoder, to tell the motor what to do. Some servos accept
